Bronsted-Lowry theory could not explain the acidic nature of $BCl_3$.

Vedclass · Answer

(A) $1$. Option $A$: The Bronsted-Lowry theory defines acids as proton donors. $BCl_3$ is a Lewis acid because it accepts an electron pair, but it does not contain a proton to donate. Thus, the theory cannot explain its acidity. This statement is correct.$2$. Option $B$: For $0.01 \ M \ NaOH$, $[OH^-] = 10^{-2} \ M$. Thus, $pOH = -\log(10^{-2}) = 2$. Therefore, $pH = 14 - 2 = 12$. The statement is incorrect.$3$. Option $C$: The ionic product of water $(K_w)$ at $25^{\circ}C$ is $10^{-14} \ mol^2 \ L^{-2}$, not $10^{-10}$. The statement is incorrect.$4$. Option $D$: The correct equation is $pH = -\log [H^+]$. The statement is incorrect.
